Abstract

This course teaches performance engineering approaches on the compute node level."Performance engineering" as we define it is more than employing tools to identify hotspots and bottlenecks. It is about developing a thorough understanding of the interactions between software and hardware. This process must start at the core, socket, and node level, where the code gets executed that does the actual computational work. Once the architectural requirements of a code are understood and correlated with performance measurements, the potential benefit of optimizations can often be predicted. We introduce a "holistic" node-level performance engineering strategy, apply it to different algorithms from computational science, and also show how an awareness of the performance features of an application may lead to notable reductions in power consumption.This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Registration

Academic participants (i.e., members of universities or public research institutions) from Europe or PRACE countries: Please apply through the PATC web page. After your registration, you will receive an automated "congratulation"-email about your successful registration. This email implies that you have a guaranteed seat in the course and you should organize your travel. All other participants (not from academia, or from outside Europe), or if the PATC web page is temporarily unavailable, please apply through this online registration form. Course number is 2014-NLP.

Deadline for Registration

15 June 2014

Fee

Members of German universities and public research institutes: noneMembers of universities and public research institutes within Europe or PRACE: noneMembers of other universities and public research institutes: 120 EUROthers: 400 EUR(includes food and drink at coffee breaks, will be collected on the first day of the course, cash only)

Cancelation policy

If you cannot come to the course, please send an email to the organizer as soon as possible. This would allow us to accept additional participants from the waiting-list. There is no cancelation fee. NO-SHOW: Registered persons that do not cancel and do not show up without any reasons are blocked for the next year on any of our workshops (because it is too expensive to produce unused copies of the slides for them).

Prerequisites

Participants must have basic knowledge in programming with Fortran or C

PRACE PATC and bwHPC-C5

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012. The mandate for the PATCs is as follows: "The PRACE Advanced Training Centres will serve as European hubs of advanced, world-class training for researchers working in the computational sciences." (see D3.2.3)This course is a PATC course, see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored through the PRACE PATC program.

HLRS is also member of the Baden-Württemberg initiative bwHPC-C5.This course is also provided within the framework of the bwHPC-C5 user Support.
